Scale for the environments evaluation of professional nursing practice—shortened version: Psychometric evaluation

Abstract

AbstractAimThe aim of this study is to test the validity and reliability of the shortened version of the Scale for the Environments Evaluation of Professional Nursing Practice (SEE‐Nursing Practice).MethodsThis methodological, cross‐sectional study was conducted between September and December 2022. The original version of the SEE‐Nursing Practice was administered in questionnaire format across 17 hospitals. Exploratory and confirmatory factor analyses were conducted to identify relevant items for the new shortened version of the scale and evaluate its construct validity.ResultsThe study involved 1713 registered nurses from various regions of Portugal. From the exploratory factor analysis, the SEE‐Nursing Practice was condensed to 59 items and 3 subscales. In the structure subscale, 14 items were removed, and the remaining 29 items distributed over four factors; in the process subscale, 18 items were removed, and the remaining 19 items organized into three factors; in the outcome subscale, 2 items were removed, and the remaining 11 items distributed over two factors. The Cronbach's alpha for the three subscales exceeded 0.90, indicating high reliability. Confirmatory factor analyses provided support for the validity of the 59‐item model.ConclusionThe shortened version of the SEE‐Nursing Practice shows adequate validity and reliability, reducing the burden associated with its longer version.
